A set of twenty elite bread wheat lines including one standard variety were evaluated in order to determine the selection criteria for identification of high yielding lines in bread wheat. The results showed that all varieties having highly significant variation for days to heading, days to maturity, plant height, 1000-kernel weight, test weight and grain yield. Grain yield was positively correlated with 1000-kernel weight and test weight while the other traits i.e, days to heading, days to maturity and plant height showed negative correlation. The results indicated that 1000 kernel weight had positive direct effect on grain yield. It was concluded that selection be made considering 1000-kernel weight and test weight.
